UNITED STATES PATENT OFFICE 2,327,122. INK ROLL CONSTRUCTION Joseph Mehlman, Los Angeles, Calif. Application February 12, 1940, Serial No. 318,435

3 Claims.

My invention relates to inking mechanisms for printing presses, and particularly to the inking rollers of such mechanisms.

It is the purpose of my invention to provide in the inking mechanism inking rollers made in sections, and wherein each section is adjustable to confine the inking to predetermined type or dies or portions of type of set-ups or forms as desired.

It is also a purpose of my invention to provide inking rollers particularly applicable to a printing press and printing numbers on perforated railway tickets, and wherein the adjusting means for any one roller provides such a fine degree of adjustment of the roller along the length of the shaft that the following advantages are obtained:

l. A part of the form can be printed without contacting the perforation in the printing of tickets having a series of coupons separated one from the other only by perforations in the paper.

2. The roller can be adjusted to compensate for very close registry of the numbering machines to print in whatever position it is desired within the blank space of the printed coupon.

I will describe only one form of sectional roller construction of an inking'mechanism embodying my invention, andwill then'point out the'novel features. thereof in claims.

Fig. 1 is a part sectional elevational view of the sectional roller construction, the sectional part being taken on the line I-I of Fig. 2.

Fig. 2 is an end elevation of one of the rollers shown in Fig. 1.

Referring specifically to the drawing, my invention in its present embodiment; comprises an inking roller I4 as including a shaft Ma, having longitudinal keyways or grooves Mb and supported as is customary inprinting presses of this type so as to be rotated. The sections [40 of the roller are provided with sleeve-hubs [4d which have key portions Me slidable in the key-ways Mb on the shaft Ma. The shaft I do is formed with a spiral series of closely spaced threaded openings I4 throughout its length for reception of threaded stop pins Mg which are adapted to engage the ends of the sleeves Md for holding the roller secincluding a round shaft having a longitudinal tions in the desired positions of adjustment for inking the plate H in spots or at spaced points as will be apparent in Fig. 1.

The afo-redescribed structure provides an adjusting means for any one roller section by which such section can be adjusted to a fine degree along the length of the shaft, and by reason of such fine adjustment, where printing tickets having a. series of coupons separated one from the other only by perforations in the paper, a part of the form can be printed without contacting the perforated rule. Moreover, each roller section can be adjusted to compensate for a very close registry of the numbering machines to print in whatever position it is desired Within the blank space of the printed coupon.

Although I have herein shown only one form of inking mechanism for printing presses, it is to be understood that various changes and modifications may be made herein without departing from the spirit of my invention and the spirit and scope of the appended claims.

I claim:

1. In a printing press, an inking mechanism in cluding a shaft having longitudinal keyways, a roller, a sleeve hub fixed to said roller and having key portions slidable in said keyways, said shaft having thereina spiral series of openings, and pins in said openings engageable with said sleeve hub for holding the roller in fixed adjustmen longitudinally on said shaft.

2. In a printing press, an inking mechanism key-way, and roller adjustable lengthwise on said shaft, and having a key portion slidable in said key-way, and coacting means on said shaft, arranged spirally to abut the ends of said roller for securing the latter in adjusted position longitudinally on said shaft.

3. In a printing press, an inking mechanism including a round shaft having a longitudinal key-way therein and openings arranged spirally therein, and roller on said shaft having a key portion slidable in said key-way and pins threaded in said openings and abutting the ends of said roller for securing the latter in adjusting position longitudinally in said shaft.
